The Pura Sunless Booths are the Rolls Royce of Automated sunless spray tanning. They don't break down like the VERSA SPAs & VERSA PROs and can use any solution you choose. We use the Cal Tan Clear Dark and Dark Tint. Much better than the Pura Solution it came with. I have two PURA booths and only need one, selling the other to make space for a UV stand up booth.
